WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 670,801. dated March 26, 1901. @preterm nea November 16,1900. sans No. 36.737. no man.)

T0 @ZZ whom t may con/cern,.-

Be it known that I, FRANKLIN P. MCOAM- MON, a citizen of the United States, residing at Whiteroek, in the county of Noble and Territory of Oklahoma, have invented new and useful Improvements in Weather-Strips, of which the following is a specification.

This invention relates to new and useful improvements in weather-strips for doors and similar structures; and its primary object is to provide a strip which is hinged to the door and normally raised out of contact with the floor or sill.

Afurther object is to provide means whereby the strip will be thrown down into contact with the sill as soon as the door is closed.

Another object is to so arrange the strip in connection with the casing to which it is secured as to prevent water from beating through the joint.

With these and other objects in View theY invention consists in providing a casing adapted to be secured to the door at a point adjacent to the lower edge thereof. Abell-crank lever is pivoted within this casing and is provided with a wristpin which engages a Slot formed within the free end of a pivoted lever. This second lever is connected by means of a link with the inner edge of the weather-strip, said strip being hinged to the lower edge of the casing and the rear edge thereof being adapted to swing in rear of said casing. A rod is pivoted to the remaining end of the bell-crank lever and extends longitudinally through the casing, projecting from the end thereof. A coil-spring incloses this rod and serves to hold the same normally projected from the casing.

The invention also consists in certain features of construction and combination of parts, which will be hereinafter fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which- Figure 1 is a front elevation of a door with my improved weather-strip secured thereto. Fig. 2 is an innerelevation of the casing and weather-strip, showing the mechanism for operating the device. Fig. 3 is an enlarged section on the line x x of Fig. 1. Fig. 4 is a section in perspective through the casing and weather-strip, showing tho means for operating the same.

In the drawings the same reference characters indicate the same parts of the invention.

1 is a door, to the lower edge of which is secured a flange 2, extending from the upper edge of a preferably metallic casing 3, which is curved in cross-section. Hinged to the lower edge of this casing are ears 4, which extend upward from a weatherstrip 5 at points between the edges thereof. This Weather-strip is preferably formed of a sheet of spring metal, the lo wer edge thereof being curved outward, thereby presenting a rounded surface to the sill of the door when said strip is depressed into contact therewith.

A bell-crank lever 6 is pivoted Within the casing 3, and one of the arms thereof is provided with a wrist-pin 7, which extends into a slot 8, formed within a lever 9 at a point adjacent to the free end thereof. The opposite end of the lever is pivoted Within the casing, as at 10. 4A link 11 extends downward from the lever 9 at a point adjacent to the slot S therein and is pivotally connected to a stud 12, extending from the Weather-strip 5 at a point adjacent to the inner end thereof. The remaining arm of the bell-crank lever is pivotally connected to a rod 13, which extends longitudinally through the casing and normallyr projects from the end thereof,the end of said rod being curved, as shown at 14. A coil-spring 15 incloses this rod and is secured at opposite ends thereto and to the casing, respectively, this spring serving to hold the end of the rod normally projected from the casing and supporting the Weather-strip in raised position. When the door is closed, the rounded end 14 of the rod 13 Will contact with the casing of the door and be forced inward thereby, expanding the spring 15. At the same time the bell-crank lever will be swung upon its pivot, carrying the slotted lever 9 upward upon its fulcrum and causing the inner edge of the weather-strip 5 to'swing up- Ward. This will obviously throw the outer IOO ward automatically, motion being imparted thereto by the spring l5. At the same time the strip and the levers will be returned to their normal position.4

If desired, a wear-plate 16 may be placed upon the casing at the point where the end of the rod 13 contacts therewith.

It will be seen that by vplacing the ears 4 at points between the inner and outer edges of the weather-strip the inner edge of said strip will be caused to swing above and in rear of the lower edge of the casing 3, and therefore any water owing downward upon said casing 3 will be prevented from passing through the joint.

Having thus described the invention, what,

is claimed, and desired to be secured by Letters Patent, is-

l. The combination with a casing; of a weather-strip hinged thereto, a bell-crank lever pivoted within the casing, a link connection between said lever and the rear edge of the Weather-strip, a rod extending through .the casing and pivoted to the lever, and means for holding said rod normally projected from the casing.

2. The combination with a casing; of a weather-strip hinged to the lower edge thereof, a bell-crank lever pivoted within the cas-l ing, a second lever pivoted therein and engaged by said bell-.crank lever, a link connection between said second lever and the inner edge of the weather-strip, a rod pivoted to the bell-crank lever and extending from the end of the casing, and means -for holding the end of said rod normally projected.

3. The combination with' a casing; of a weather-strip, ears thereto at points between the edges thereof, said ears being hinged to the casing, a bell-crank lever pivoted within the casing, a slotted lever pivoted within said casing and engaged by the bell-crank lever, a stud extending from the inner edge of the Weather-strip, a link connection between said stud and the slotted lever, a rod pivoted to the bell-crank llever and extending from one end of the casing, and a spring inelosing the rod and adapted to hold the same normally projected. y Y

In testimony whereof I aX my signature in presence of two witnesses.

FRANKLIN P. MGOAMMON.
